# LangChain MCP connector

The LangChain connector links your LangChain sessions, session views, insights and insight configs to Claude, ChatGPT, Cursor and other MCP clients through one Elaichi endpoint, so each person works in LangChain as themselves with every action logged.

| Application | LangChain |
| Category | Artificial Intelligence |
| AI tools | 382 |

| MCP endpoint | https://api.elaichi.ai/mcp |
| Works with | Claude, ChatGPT, Cursor, any MCP client, and the Elaichi Agent |
| Tools advertised by name | No. 382 tools is past the 30-tool threshold, so clients use `search_tools` and `execute_tool` |

## What you can ask once LangChain is connected

- Summarize this week's LangChain sessions by status.
- Which session views changed most in the last 14 days?
- List sessions missing metadata from last week's runs.

## Connect LangChain in Elaichi

This happens once for the organization, before any client is involved.

1. Open Connections, choose Add connection, and pick LangChain.
2. Optionally set Share with, then press Connect.
3. Paste a LangChain API key. One person generates a token in LangChain and pastes it once. Everyone else works through Share with, and never sees it.

Credentials are vaulted and nobody, including the AI, reads them back. The connection becomes a toolbox immediately, so you can curate which LangChain tools are exposed, rename them, or freeze arguments before anyone points a client at it.

## Connect LangChain to Claude

Endpoint: https://api.elaichi.ai/mcp

1. Open Customize, then Connectors.
2. Press Add.
3. Name it, paste the MCP server URL, then Continue.
4. Sign in and approve.

On Team and Enterprise, an Owner adds it once. Everyone else turns it on for themselves.

## Connect LangChain to ChatGPT

Endpoint: https://api.elaichi.ai/mcp

1. Open Plugins, then press the + button.
2. Name it and paste the endpoint into Server URL.
3. Leave Authentication on OAuth, then tick the risk acknowledgement.
4. Press Create, then sign in and approve.

Works on the web today. The plugin directory lives at chatgpt.com/plugins.

## Connect LangChain to Cursor

Endpoint: https://api.elaichi.ai/mcp

1. Open `~/.cursor/mcp.json`.
2. Add the endpoint under `mcpServers`.
3. Reload Cursor, then sign in and approve.

Set up per machine, so repeat it on each computer you work from.

## Connect LangChain to any MCP client

Endpoint: https://api.elaichi.ai/mcp

1. Add the endpoint as a remote MCP server.
2. Sign in and approve.

The Elaichi Agent already has these tools, with nothing to set up.

## What the consent screen decides

Only Read is granted by default, which is not enough to call a LangChain tool. Over MCP there is no trusted place to confirm a write in the moment, so the consent screen is the standing approval rather than a formality. Grant Read and Run tools. Think hard before granting Delete, which reaches into connected apps and cannot be undone.

## What teams do with LangChain through Elaichi

### Check on a session before standup

Engineering. Ask for the dashboard of a LangChain session by name and get a plain summary of how it is doing, without opening another tab.

### Set up a new session for a launch

Engineering. Create a LangChain session for a new feature, then rename or update it later as the project changes shape.

### Turn a question into a saved view

Product. Describe what you want to see and have a LangChain session view created for it, then rename a batch of views in one go when naming conventions change.

### Read the insights on a session

Data science. Pull the session insights LangChain has generated, ask what stands out, and create or adjust an insights config to change what gets tracked next.

### Tidy up old sessions in bulk

Operations. List every LangChain session, spot the ones nobody has touched, and delete them together once the team agrees.

### Confirm LangChain is healthy during an incident

Support. Check LangChain's health status and the metadata on the affected session so you can tell customers what is going on with confidence.

## Frequently asked questions

### How do I connect LangChain to Claude?

Connect LangChain in Elaichi first, which asks for your LangChain API key and nothing else, so there is no OAuth application to register and no client ID or secret to generate. Then in Claude open Customize, then Connectors, then Add, and paste https://api.elaichi.ai/mcp. Sign in with your Elaichi account when prompted and LangChain is ready to use in Claude.

### Does LangChain work with ChatGPT and Cursor as well as Claude?

Yes. Once LangChain is connected in Elaichi, the same endpoint, https://api.elaichi.ai/mcp, works in Claude, ChatGPT, Cursor, any other MCP client and the Elaichi Agent. You connect LangChain once and every client picks it up.

### What can an AI agent actually do with my LangChain data?

An agent can list your LangChain sessions, open a session's dashboard and describe how it is performing, create or rename sessions and session views, and read or create session insights and insight configs. It can also check LangChain's health and pull session metadata when something looks off. LangChain has a large set of actions, so short concrete asks like "show me the dashboard for the checkout session" work better than long paragraphs.

### Does connecting LangChain give the AI access to every session in my workspace?

No. Access follows the LangChain API key of the person who connected it, so an agent only sees the LangChain sessions, views and insights that key already reaches. Elaichi can narrow that further with per-action restrictions, and it can never widen it beyond what LangChain itself allows.

### Can my team share one LangChain connection?

Yes. One person connects LangChain in Elaichi and shares the connection with a team, and nobody else ever handles the LangChain API key. Each teammate still signs in to Elaichi as themselves, so the audit log names the person behind every session change, not the connection.

### Can I stop an agent from deleting or changing things in LangChain?

Yes. Restrictions in Elaichi work per action, so you can allow reading LangChain sessions and insights while blocking deleting sessions, bulk deleting or editing insight configs. A blocked action is never shown to Claude, ChatGPT or Cursor at all, so no prompt can reach it.

### What happens to a LangChain connection when someone leaves?

Offboarding a person in Elaichi ends their access to LangChain at once, across every client they used. A shared LangChain connection keeps working for everyone else on the team. If you want LangChain gone entirely, disconnecting it once in Elaichi removes it from Claude, ChatGPT, Cursor and every other client.
